Two-Step Converging Spherical Wave Diffracted at a Circular Aperture of Digital In-Line Holography
The aspheric light emitted from a pinhole restrains the reconstruction quality of a digital in-line hologram. Herein, the Fresnel-diffracted spot from the first step converging spherical wave diffracted at a rough circular aperture is collimated and expanded to generate an even plane wave, which is...
